Description

[Detailed description of the invention] The present invention is a separate electric cooking device that uses a combination of the appliance body and its support, which makes it impossible to apply electricity to the appliance body alone, thereby improving safety. Regarding cooking equipment.

In general, with this type of separate cooker, if only the main body of the hot plate, which has a heating element integrally cast into it, is placed directly on a table etc. and energized, the heat of the plate may scorch the table or cause a fire. There is a risk of outbreak.

For this reason, it is necessary to either make it impossible to conduct electricity when the plate is separated from the support, or to have a structure that is safe even if electricity is applied.

As a countermeasure to this problem, conventional plug-in thermostats (temperature controllers that also serve as plugs) have been equipped with a microswitch, and the microswitch circuit is connected and energized only when the device body and its support are properly assembled. However, it has the drawback that it requires a separate microswitch and a case to protect the microswitch, which increases the cost. However, since it is different from the conventional type, it has drawbacks such as not being able to be used commonly.

The present invention was developed to eliminate the above-mentioned drawbacks, and in a separate type electric cooker, an elastic linear stopper is disposed approximately in front of the center of the heat-sensitive rod insertion hole formed in the appliance body, so that the normal combination can be achieved. It is an object of the present invention to provide an electric cooking appliance in which the stopper deforms to open the insertion hole only in the case where a plug-in thermostat can be connected, thereby improving safety.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, details of the present invention will be explained with reference to the drawings for one embodiment.

1 is, for example, a hot play 1 that houses a heating element 2 on the bottom.
A main body of an electric cooker such as ・A rod-shaped body connected to the heating element 2 and terminal portions 3, 3 are arranged on one side thereof,
Further, an insertion hole 6 for receiving a temperature sensing rod 5 of a plug-in thermometer 4 is provided between the terminal portions 3, 3.

A protector 7 is attached to one side of the instrument body 1 so as to cover the terminal parts 3, 3 and the insertion hole 6, and a part of the bottom surface 7' extending downward of the body 1 has a protector shown in FIG. As shown in the exploded perspective view, a pair of wall portions 8, 8 are provided upright near the opening surface of the insertion hole 6, and a transparent hole is provided adjacently to one end side of the bottom surface 7'' between these wall portions 8.8. (L9 is provided.

Reference numeral 10 denotes an elastic linear stopper, and one end thereof has a bent portion 10a that abuts the bottom surface 7'' and is located between the wall portions 8.
The other end is inserted into the instrument main body 1, and the insertion hole 6 is held so as to be vertically partitioned approximately at the front center thereof.

Reference numeral 11 denotes a support formed in a frame shape, and inside in the longitudinal direction there are support parts 1 into which handles 12 and 12 of the instrument body 1 fit.
A recess 14 into which the protector 7 fits is provided on one side edge in the width direction, and a columnar projection having a retaining portion 15 on the upper surface is provided on the inner edge of the recess 14. 16 are provided.

Next, we will discuss the effect.

When the instrument body 1 and the support body 11 are separated,
As shown in FIG. 7, the elastic stopper 10 is located so as to separate the front part of the insertion hole 6, so that even if an attempt is made to insert the plug-in thermostat 4 into the protector 7, the thermosensitive rod 5 will not touch the insertion hole 6 in order to conduct electricity. Insertion is prevented by the stopper 10 and cannot be inserted.

Therefore, electrical connection to the terminal portions 3, 3 cannot be made.

Furthermore, when the instrument body 1 and the support 11 are properly engaged, the protrusion 16 in the recess 14 of the support 11 is inserted into the through hole 9 of the protector 7, and the engagement portion is inserted into the protector 7. 15 comes into contact with the bent portion 10a of the elastic stopper 10 and pushes it up.

In addition, at this time, the above-mentioned retaining part 15 has both side edges 15a,
Since the stopper 15b is erected in a step-like manner, the pushed-up stopper 10 has elasticity that causes the lower side edge 15a to
The insertion hole 6 is curved and deformed in the direction shown in FIG. 7 to the state shown in FIG. 8, and the insertion hole 6 is opened.

Therefore, electrical connection can be made without causing any obstruction to the insertion of the plug-in thermostat 4.

Furthermore, when the instrument main body 1 is separated from the support 11, the pressure on the stopper 10 by the retaining portion 15 is released, and the elastic restoring force of the stopper 10 causes the heat-sensitive rod 5 to return to the front center of the insertion hole 6. can be prevented from being inserted.

As described in detail above, the present invention is a separate type electric cooker consisting of an appliance body and a support body, and the front part of the insertion hole is separated between the body and a protector that covers the terminal part and the heat-sensitive rod insertion part. An elastic stopper is arranged as shown in FIG. Since the electric cooking appliance is equipped with a protrusion that opens and closes, the plug-in thermometer can be inserted and energized only when the appliance body and support body are properly assembled.

Therefore, even if an attempt is made to energize the appliance main body in a separated state, the plug-in thermometer cannot be inserted, thereby eliminating the risk of fire or the like, thereby providing the advantage of significantly improving safety.

In addition, since there is no need to provide a special additional device such as a microswitch, the plug-in thermometer can be used in common with general products.

Furthermore, since the stopper is made of an elastic material, it does not require a separate return spring material, and has advantages such as a simple structure and low cost.
